I definitely love Sword Art Online~ It's been really great so far with every episode, and I'm always really excited to sit down on Saturdays and watch. The character's and their outfits are gorgeous as well. c:
I also love Tari Tari and Kokoro Connect, as they too have great storylines, and cute characters.

The little arc with Kushina and Minato was one of the more memorable moments of this year as far as anime goes for me. If I only consider that handful of episodes, it's easily up there with Fate/Zero and Chihayafuru.

Fate/Zero was simply incredible, so that is probably my pick for best, but depending on how the last few episodes of SAO turn out, it may move up the list. I haven't read the original work so I have no clue what's to come. Even so, they are going to have to be pretty damn good to make the series better than Fate or Chihayafuru.
